I'm rebuilding the fuel pumps (along with generally cleaning/overhauling many systems) on my 1963 Merc 850.

First of all, for anyone interested, I wanted to post a link to a parts fiche for this pump. I and a few others whose posts I found have taken them apart and not been positive how the valves go back in. It is evident how they go in by looking at this parts fiche and it confirmed the way that I was pretty sure that I remembered them coming out. I wanted to post this because I couldn't find this information anywhere else on here...most of the other questions were answered with passive-aggressive comments about purchasing a factory manual.

Secondly, I was wondering if I ought to use a gasket sealer on any of the gaskets in the assembly (the stuff you use on water pumps and the like) or will it just end up breaking down and collecting in my float bowls?

I will also edit this post by adding some pictures to aid others in the future.

Any info will be a great help.

NO!!!! Fuel pump gaskets are assembled dry and your assumption of it breaking down and getting its system is correct....
